AWS Beanstalk (running Spring Boot jar) and Log aggregation with ElasticSearch & Filebeat

Most serious applications (and distributed microservices style architectures) will require to provide a log aggregation & analysis feature to its dev & operations teams. Reviewing log entires from 10s or 100s of server instances is not something to take lightly. Whether you choose to use a commercial product or an open source offering – that does not matter; just make sure you have one available.

Log messages can be routed to a Lambda function which would break the log messages into individual attributes suitable for indexing. I wanted to try a slightly different route where I depend less on CloudWatch Logs and more on open source tools. Enter filebeat on Beanstalk.

It is hard not to be affected by the constant chatter on Microservices Architecture and Container technology. Both are leading the discussions nowadays and they combine to provide new ways to Architect distributed systems and provide agility in delivering business value. While they do bring in big benefits when implemented successfully, the path to success for most enterprises (other than startups/product/tech firms) is going to be difficult and having a level of measured caution would be good.

From using physical machines we moved to virtual machines (somewhere in between a few brave folks also used linux/solaris containers). The current trend is container technologies such as Docker or CoreOS RKT which allow even more efficient use of resources. Regardless of which you use, we are often required to plan our application infrastructure needs upfront and permanently keep the “servers” running.
